fix(profiling): alternative import type (#44507)

~Alternative to https://github.com/getsentry/sentry/pull/44506, benefits
of this approach is that we only re-import once and the state is
synchronously propagated to the children.~

Why did I forget useMemo exists, I do not know, but we should use it
here instead.
